Nine kilometres southeast of St-Benoît, the Château de Sully-sur-Loire is a grand example of a fairy-tale castle, built from 1395 with machicolated ramparts and turrets to defend one of the Loire's crucial crossings. From the outside this is one of the region's most picturesque châteaux, rising from a glassy moat lined by stately bald cypresses (brought from the United States by General Lafayette in the late 1700s). The castle has an impressive exposed vaulted roof and historic tapestries depicting the story of Psyche.
An outdoor music festival (www.festival-sully.com) jams in late May and early June.
